title: Age estimation from the number of teeth erupted in young children: an aid to demographic surveys.
abstract: The reporting of children's ages by parents is surprisingly inaccurate in many innumerate societies, but accurate knowledge of age is important for estimating recent changes in demographic rates. The timing of the eruption of children's teeth is largely independent of environmental influences and can provide a relatively accurate and unbiased estimate of a child's age. We have collected published data from 42 studies of children's dentition and have transformed them into estimates of age for children with particular numbers of teeth. We present estimates for different populations, but the lack of significant differences between these estimates justifies the use of a standard set.
